However, some users find the device to be quite loud and heavy, impacting the overall styling experience.

    Honestly, I had looked at another brand because of Facebook ads, but it was not available. I decided to give the Shark styling system a try. I’m SO glad I did!! It is amazing! I would not hesitate to purchase it again in the future!

    I bought this dryer because of its many options and good reviews. However, if you are the type of person who is not tolerant to noise, I would recommend passing on this hair dryer.

    The blow dryer is loud but it dries your hair fast. I love the hair straightener because it makes my hair straight for days. I don’t like the other attachments. I find the other attachments difficult to use.

    Got for Christmas for my daughter that has curly-ish hair, she loves the straightening feature, along with the root blowdryer. Make sure when your looking that the FlexFusion has the straightner attachment, many online don't!

    My 15 y/o daughter received this as a gift. She likes the straightener but has not yet mastered how to use the curling tools. It is VERY loud!!!! Which would be my only complaint with it.
